Fujino | November 12, 1996 |
The cordless telephone system according to the present invention comprises a synchronization inhibiting circuitry for inhibiting, when a calling station sends a communication end request code, synchronization with a called station in communication therewith for a prespecified inhibit time after transmission of the communication end request code, and a communication terminating circuitry for terminating communication if a state where synchronism with the called station is lost continues for a prespecified reference time during communication. Thus, communication is terminated without fail when a call ends, and transactions of unnecessary electric waves are reduced.
